Application March 23, 1944, Serial No. 527,802

' 6 Claims. (01. 24 2o5) This invention relates to separable fasteners employing stringers with a slider movable along the stringers to couple and uncouple the same. More particularly, the invention relates to the provision of means on at least one stringer and on the slider for checking movement of a slider along the stringers. Further, the invention also includes the provision of a tentative end stop beyond which the slider is capable oi? forceable movement in completely separating the stringers at said stop end thereof. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a detail view of one end portion of a pair of stringers, showing a slider thereon in a normal stop position, the slider being shown in section.

Fig. 2 is a partial section on the irregular line 2--2 of Fig. 1.

Fig. 3 is an enlarged perspective view of the slider detached.

Fig. 4 is an enlarged perspective view of one of the stop members which I employ shown in a detached and open position preparatory for mounting on a stringer; and

Fig. 5 is a reduced detail view of one stringer showing a spaced arrangement of stop or check members thereon, the slider being shown in sec-.

tion.

In Fig. l of the drawing the upper or normally closed end portion of two stringers I0 and H is shown having links or scoops I2 arranged on the beaded edge portions l3 of the stringer tapes. Further, the illustration of Fig. 1 shows my improved stop or check construction applied to what is termed a quick pull apart fastener which can be pulled apart and separated at said stop end. This is accomplished by providing beyond the end link it of the stringer H a blank space IE on the beaded edge a distance sumcient to freely clear the tape and beaded edge i3 through one open side of a slider it. That is to say, between the inturned flanges H on the opposed top and bottom walls I8 and H of said slider.

Similar inturned flanges H are provided at the other side of the slider, as will clearly appear in Fig. 3 of the drawing, and the fianges H at both sides of the slider include at the inner contracted ends thereof inwardly projecting members 20 which produce restricted areas 2|, for purposes mal closing movement of the slider.

later described. Considering Fig. 1 of the drawing, the stringer I0 includes a number of links 22, which extend beyond the end link I4 of the stringer I I, and are suflicient in number to position the contracted end 23 of the slider in a position to freely clear the end link M in the pull apart separation of the stringers Ill and H. In this position, the end 24 of the walls l8 and H! of the slider will be in engagement with a stop 25 arranged on the stringer l0 beyond the end link thereon.

-Arranged on the stringer ll inwardly of but adjacent the end link I4, is a stop or check device 28, which in the construction shown, comprises a member consisting of two side plate portions 21 joined by two or more spaced loops 28. The loops 23 are of such width as to fit freely between adjacent links of the stringer, and are of such diameter as to envelop the beaded edge l3 of the stringer to dispose the plates 21 upon the surfaces of the stringer tape inwardly of the bead l3. This construction produces on both upper and lower surfaces of the tape, at inner ends of the links or scoops, bearing surfaces adapted to be engaged by the projections 20 at the contracte end of the slider.

From the foregoing, it will be apparent that when the slider is moved into the closed position as shown in Fig. l of the drawing, and also indicated in Fig. 2, the projections 20 will strike the ends of the bearing surfaces 21 and check nor- However. by applying force to the slider, the projections 20 are caused to ride-up onto and pass over the surfaces 21, the walls l8 and W are slightly yieldable and adapted to be sprung apart in this operation, and thus the slider is free to move into the final stop position in engagement with the stop 25 at which position of the slider the stringers l0 and i l are free to be pulled apart.

In some instances, the stop or check member 25 may be composed of strip or sheet material, and formed in the open position illustrated in Fig. 4 of the drawing, and then afterwards mounted on and secured to the stringer tape by compression of the Wall or projecting stop por tions 21 toward each other. When these devices are composed of plastic material, as they may be in plastic fasteners, the member 26 may first have to be heated before shaping or forming the same into the final attached position upon the stringer.

In Fig. 5 of the drawing another adaptation and use of the invention is illustrated. In this figure, a stringer 29 has two check or stop devices 30 and 3| arranged at spaced intervals along the beaded edge 32 of the stringer, and arranged between predetermined spaced links or scoops 33 thereon. The outermost stop or check device 30 being arranged inwardly of and in spaced relation to the end stop 34.

It will appear from a consideration of Fig. 3 of the drawing that the ends 20a and 20b of the projection 20 are rounded, thus producing camming surfaces which will permit torceable movement of the slider over the devices 30 and 3| in either direction, thus it will appear that movement of a slider in the direction of the stop 34 on the stringer 29 may be first checked by the device 3|. The slider may be forceably moved over the device 3|, and then checked by the device 30, thus disposed between the devices 30 and 3|. Still further, the slider may be iorced over the device 30, and then retained between the device 30 and the stop 34. However, to again open or separate the stringers, the slider may be moved in the opposite direction to be forceably passed over the device 30 and then iorceably passed over the device 3|.

While many adaptations and uses may be employed for the spaced stop or check devices, one practical illustration would be in checking opening movement of a shirt, sweater, jacket or similar article of apparel, to produce for example, difierent neck openings, while at the same time, retaining a slider against accidental opening movement on the stringers in any position which may be assumed thereby in the partially open position.

Furthermore, these devices will check sliders against opening movement in their final stopped or closed position. In other words, the distance of the outer end of the device 30 with respect to the stop 34 may equal the length of the slider. That is to say, to position the projecting members 20 slightly beyond the devices 30 when the slider is in engagement with the stop 34. Thus to open the slider, a. forceable downward movement of the slider or movement away from the stop 34 would be required. This construction will dispense with the use of the conventional securing means commonly employed on sliders to check opening movement thereof. v

The devices 30 and 3| are of the same construction as the device 26, except that only two rings orioops 35 are employed, and these loops are joined by wall portions 36 similar to the wall portions 21. v

In the devices 26, 30 and 3|, the wall portions 21 and 36 extend onto the tapes only a slight distance, namely a, distance to be engaged by the projections 20 011 the flange portions ll of the slider. Thus the devices 25, 30 and 3| become substantially invisible upon the stringers, particularly if these devices are composed of materials having the same or substantially the same color as the color employed in the scoops. Where conductor wires are employed in the tapes or the beaded edges thereof, as taught in my prior Patent'Number 2,063,515 dated December 8, 1936, and the stop or check devices are composed of metal, contact will be established with these conductors wires to facilitate plating the top or check devices with a plating common to the plating applied to the links or scoops, thus maintaining the same appearance thereof.

One of the distinctive features of the present construction resides in the fact that the. stop or check devices can be readily applied to stringers without altering or interfering in any way with the structure of the stringers, and-can be applied to meet specific requirementsoi a manufacturer or even the resultant purchaser, it being understood that the devices can be readily applied by a merchant in the store in which the purchase is made. Suitable tools will be provided for this purpose. In this sense, the stop or check devices may be made to suit the fancies or desires. of a purchaserin any particular garment or article of manufacture which would require theuse of such devices. In fact, in making the devices of a sufiicient pliable or spring material, a purchaser may from time to time, shift the devices on the stringer or stringers in altering the stop or check positions of the slider thereon.
